What you can do with the demo version

A CRYSTAL14 evaluation copy is available free of charge for Linux and Windows operating systems. All functionalities of the full version are active, the only limit is the number of atoms, restricted to 20 per primitive cell. CRYSCOR09 is also part of the CRYSTAL14 demo version with the limit of 3 atoms per primitive cell.
For a quick introduction to CRYSTAL input and output a guided "CRYSTAL tour" is suggested.

Here below some example of systems that can be studied with the evaluation version of CRYSTAL14.
